      The picture shows that the confocal architecture permits photon counting statistics to be collected from two-dimensional structures or surfaces containing fluorescent molecules at low concentrations. The resulting photon-counting histograms provide information about the surface concentration and brightness (or photophysics) of the molecules of interest, as shown on p. 2439 by N. O. Petersen et al.

    1. Atomic Ensemble Effects in Electrocatalysis: The Site-Knockout Strategy (pages 2375–2385)

      Dr. Angel Cuesta

      Version of Record online: 5 JUL 2011 | DOI: 10.1002/cphc.201100164

      Thumbnail image of graphical abstract

      It′s a knockout! Removing only one kind of site from the surface of a single-crystal electrode with a regular array of an inert adsorbate, while leaving the electronic properties of the atoms that remain free unaffected (the site-knockout strategy, see picture), is the most appropriate way to study atomic ensemble effects without interference from electronic effects. Cyanide-modified Pt(111) surfaces, as reviewed here, are particularly suitable for this kind of study.

      Version of Record online: 6 JUL 2011 | DOI: 10.1002/cphc.201100392

      Thumbnail image of graphical abstract

      Resolving aggregates: Single-molecule super-resolution imaging of fluorescent Huntington′s disease proteins reveals the detailed morphology of aggregates in aqueous environments (see figure, color) and shows excellent agreement with atomic force microscopy images (figure, black) of the same aggregates.

    2. Triple Emission from Organic/Inorganic Hybrid Nanovesicles in a Single Excitation (pages 2391–2396)

      Yemineni S. L. V. Narayana and Prof. Rajadurai Chandrasekar

      Version of Record online: 12 JUL 2011 | DOI: 10.1002/cphc.201100426

      Thumbnail image of graphical abstract

      Luminescent Vesicles: Triple-color-emitting organic/inorganic nanovesicles are successfully prepared through a stepwise self-assembly approach. This innovative “bottom-up” methodology can be used to fabricate multi-luminescent soft organic/inorganic hybrid nanostructures displaying diverse colors.

    3. Imaging the Active Surfaces of Cerium Dioxide Nanoparticles (pages 2397–2399)

      Dr. Sarah J. Haigh, Dr. Neil P. Young, Dr. Hidetaka Sawada, Prof. Dr. Kunio Takayanagi and Prof. Dr. Angus I. Kirkland

      Version of Record online: 14 JUL 2011 | DOI: 10.1002/cphc.201100376

      Thumbnail image of graphical abstract

      Watching the changes: Aberration-corrected transmission electron microscopy is used to image CeO2 nanoparticles during an electron-beam-induced structure transformation. Analysis of the phase of the computationally restored exit wavefunction (see Figure, a) allows the nature of the different surfaces (b) to be characterized for the first time and provides direct experimental verification of previously reported theoretical surface structure calculations.

    4. Understanding the Dissolution of Polyols by Ionic Liquids Using the Example of a Well-Defined Model Compound (pages 2400–2404)

      Zakar Papanyan, Christian Roth, Dr. Dietmar Paschek and Prof. Dr. Ralf Ludwig

      Version of Record online: 13 JUL 2011 | DOI: 10.1002/cphc.201100437

      Thumbnail image of graphical abstract

      Break the bond: The dissolution strength of ionic liquids and traditional solvents is studied spectroscopically and computationally for a well-defined model compound of polyols (see picture). Due to a strong hydrogen bond network the alcohol pentaerythritol closely resembles the natural polymer cellulose. Not only the ionic character of the solvent but in particular strong interacting anions are essential for disrupting the hydrogen bond networks and are crucial for its dissolution power.

    5. Prediction of a New Delocalised Bonding Motif between Group 15 or Group 16 Atoms (pages 2405–2408)

      Prof. Dr. Michael Bühl, Dr. Petr Kilian and Prof. Dr. J. Derek Woollins

      Version of Record online: 8 JUL 2011 | DOI: 10.1002/cphc.201100423

      Thumbnail image of graphical abstract

      Fixed bonds: Using suitably constrained molecular scaffolds, electron delocalisation over four centers can be enforced in X-E-E-X moieties (where E=group 15 or 16 element, X=acceptor, see picture). Identified through DFT calculations, a new facet of chemical bonding is waiting to be discovered.

    6. Broadband 13C-Homodecoupled Heteronuclear Single-Quantum Correlation Nuclear Magnetic Resonance (pages 2409–2411)

      Mohammadali Foroozandeh, Dr. Patrick Giraudeau and Dr. Damien Jeannerat

      Version of Record online: 12 JUL 2011 | DOI: 10.1002/cphc.201100411

      Thumbnail image of graphical abstract

      13C-homodecoupling in F1: Eliminating homonuclear 13C scalar couplings is a challenging NMR problem when enriched compounds are studied by NMR. The 13C-homodecoupled heteronuclear single-quantum correlation (HSQC) experiment (BBHD-HSQC) relies on the Zangger–Sterk pulse sequence element to combine spatial encoding of the chemical shift with the refocusing of couplings. The sequence is applied to fully enriched 13C cholesterol.

    7. Hierarchical ZnO Structure with Superhydrophobicity and High Adhesion (pages 2412–2414)

      Dr. Liqiu Zheng, Prof. Zhongrui Li, Dr. Shawn Bourdo, Viney Saini, Dr. Charles Ryerson and Prof. Alexandru S. Biris

      Version of Record online: 12 JUL 2011 | DOI: 10.1002/cphc.201100314

      Thumbnail image of graphical abstract

      Any petal but a lotus: The hierarchically structured ZnO surface presents superhydrophobicity and a distinctive solid–liquid adhesion that can be attributed to the suitable size of nanostructures in combination with microscopic structures (see picture). Although the surface is superhydrophobic, water droplets continue to cling to the surface even when it is overturned.

    8. Sensitization of TiO2 with Pt, Pd, and Au Clusters Protected by Mercapto- and Dimercaptosuccinic Acid (pages 2415–2418)

      Dr. Nobuyuki Sakai, Takahiro Ikeda, Prof. Toshiharu Teranishi and Prof. Tetsu Tatsuma

      Version of Record online: 12 JUL 2011 | DOI: 10.1002/cphc.201100223

      Thumbnail image of graphical abstract

      Noble behavior: Pt, Pd, and Au clusters protected by mercapto- and dimercaptosuccinic acid serve as sensitizers for TiO2. Pt and Pd clusters give higher photocurrents than Au clusters, and the photocurrents are further improved by employing an electrolyte containing iodide ions as electron donors, in which Au clusters are corroded (see picture).

    9. Accurate Quantum Dynamics Study on the Resonance Decay of Vinylidene (pages 2419–2422)

      Bin Li, Yinghui Ren and Prof. Wensheng Bian

      Version of Record online: 30 JUN 2011 | DOI: 10.1002/cphc.201100144

    1. Borane Derivatives: A New Class of Super- and Hyperhalogens (pages 2423–2428)

      Biswarup Pathak, Devleena Samanta , Prof. Dr. Rajeev Ahuja and Prof. Dr. Purusottam Jena

      Version of Record online: 27 JUL 2011 | DOI: 10.1002/cphc.201100320

      Thumbnail image of graphical abstract

      More than halogens: A new class of clusters based on boranes and carboranes, for example, B12H13 (see picture), are shown to have electron affinities far exceeding those of halogen atoms. These super- and hyperhalogens, formed according to the Wade–Mingos rule, open the door to the design of highly electronegative species which can also serve as weakly coordinating anions.

    2. Spin–Orbit Coupling in Phosphorescent Iridium(III) Complexes (pages 2429–2438)

      Arthur R. G. Smith, Prof. Paul L. Burn and Prof. Ben J. Powell

      Version of Record online: 22 JUL 2011 | DOI: 10.1002/cphc.201100397

      Thumbnail image of graphical abstract

      Exciting couples: The excited-state properties of two iridium(III) complexes with potential applications in organic light-emitting diodes are calculated (see picture). An indirect relativistic stabilisation of the metal-to-ligand charge transfer states increases the effectiveness of spin–orbit coupling in hybridising singlet and triplet states, thus enhancing phosphoresce.

    3. Photon Counting Histogram Analysis for Two-Dimensional Systems (pages 2439–2448)

      Dr. Max Anikovsky, Zach D. Wiltshire, Dr. Klaus Weisshart and Dr. Nils O. Petersen

      Version of Record online: 29 JUL 2011 | DOI: 10.1002/cphc.201100414

      Thumbnail image of graphical abstract

      New analysis for 2D structures: Photon counting histogram analysis can now be performed on 2D structures (see picture). In addition, it is shown that data for analysis can be retrieved from confocal images, which broadens the applicability of the new method.

    4. Surface-Plasmon-Coupled Emission of Rhodamine 110 in a Silica Nanolayer (pages 2449–2452)

      Simeonika Rangełowa-Jankowska, Dawid Jankowski, Dr. Beata Grobelna, Prof. Ignacy Gryczyński, Prof. Zygmunt Gryczyński, Dr. Robert Bogdanowicz and Prof. Piotr Bojarski

      Version of Record online: 12 JUL 2011 | DOI: 10.1002/cphc.201100252

      Thumbnail image of graphical abstract

      First come, first see: The first observation of strong directional surface-plasmon-coupled emission (SPCE) of Rhodamine 110 in silica nanofilms deposited on silver nanolayers is reported. The picture shows SPCE in daylight (left) and in a dark room (right).

    5. Can a Proton be Encapsulated in Tetraamido/Diamino Quaternized Macrocycles in Aqueous Solution and Electric Field? (pages 2453–2460)

      Dr. Nan Jiang  and Prof. Jing Ma

      Version of Record online: 17 AUG 2011 | DOI: 10.1002/cphc.201100229

      Thumbnail image of graphical abstract

      Proton encapsulation in water-solvated tetraamido/diamino quaternized macrocycles depends on whether the bridge linkages are rigid (phenyl) or flexible (propyl) and the influence of an external electric (E) field. When an E field is applied, the proton migrates from the macrocyclic framework to the water in the former case, but it can still be encapsulated in the latter (see picture).

    6. Brookite TiO2 Nanoparticle Films for Dye-Sensitized Solar Cells (pages 2461–2467)

      Constance Magne, Dr. Sophie Cassaignon, Gilles Lancel and Dr. Thierry Pauporté

      Version of Record online: 12 JUL 2011 | DOI: 10.1002/cphc.201100194

      Thumbnail image of graphical abstract

      Brookite-based solar cells: Porous layers are prepared from brookite TiO2 nanoparticles grown at low temperature by a soft solution synthetic method; these are sensitized and used to fabricate dye-sensitized solar cells. Particles with a crystallite size of 20 nm give rise to the best cells, reaching an overall conversion efficiency of about 6.0 % without a scattering layer (see picture).

    7. A DFT Investigation of Surface-Enhanced Raman Scattering of Adenine and 2′-Deoxyadenosine 5′-Monophosphate on Ag20 Nanoclusters (pages 2468–2475)

      Xiu-Feng Lang, Prof. Peng-Gang Yin, Ting-Ting You, Li Jiang and Prof. Lin Guo

      Version of Record online: 6 JUL 2011 | DOI: 10.1002/cphc.201100187

      Thumbnail image of graphical abstract

      Adenine–Ag20complexes in which adenine is adsorbed on the tetrahedral silver cluster through N3 (see picture) allow typical experimental surface-enhanced Raman spectra (SERS) in silver colloids to be reproduced in DFT calculations, which predict that the ring-breathing mode tends to dominate the SERS of adenine.

    8. Compressibility of Gas Hydrates (pages 2476–2484)

      Dr. Andrey Yu. Manakov, Dr. Anna Yu. Likhacheva, Dr. Vladimir A. Potemkin, Dr. Andrey G. Ogienko, Dr. Alexander V. Kurnosov and Dr. Aleksei I. Ancharov

      Version of Record online: 29 JUN 2011 | DOI: 10.1002/cphc.201100126

      Thumbnail image of graphical abstract

      Rapid expansion: Some new experimental data on the pressure dependence of unit cell parameters for the gas hydrates of ethane, xenon, and the double hydrate of tetrahydrofuran+ xenon are presented. Available data on compressibility of gas hydrates within different pressure ranges are discussed (see picture).

    9. p-Nitrobenzoic Acid Adsorption on Nanostructured Gold Surfaces Investigated by Combined Experimental and Computational Approaches (pages 2485–2495)

      Dr. Jarosław J. Panek, Dr. Aneta Jezierska-Mazzarello, Prof. Aleksander Koll, Prof. Galina Dovbeshko and Dr. Olena Fesenko

      Version of Record online: 12 JUL 2011 | DOI: 10.1002/cphc.201100067

      Thumbnail image of graphical abstract

      Low angle, high enhancement: Surface-enhanced infrared absorption is measured for p-nitrobenzoic acid on rough Au surfaces (see picture). A specially selected low-incidence angle allows registering of large enhancement factors simultaneously for many modes, while DFT calculations show the preferred adsorption mode.
